(8405) Asbolus is an asteroid belonging to the group of centaurs .

He was born on 5. April 1995 by James V. Scotti and Robert Jedicke from Space Watch project at the Observatory of Kitt Peak discovered.

The provisional name was 1995 GO . Because of its dark surface, it was named after Asbolus , a centaur from Greek mythology .

Asbolus moves on a very eccentric orbit between 6.835 AU ( perihelion ) and 29.028 AU ( aphelion ) around the sun in 75.93 years . It thus moves between the planets Jupiter and Neptune . The orbit is inclined 17.6 ° to the ecliptic .

Asbolus' mean diameter is estimated to be 66 km (± 8 km).

In the year 2000, spectra of Asbolus were recorded with the Hubble Space Telescope , which revealed an unusually bright structure on its surface, which is believed to be a relatively young crater . The ice responsible for the structure seems to be of a previously unknown type. The impact cannot be more than 10 million years ago. Otherwise the surface is very dark with an albedo of 0.09.

As with the rest of the centaurs, Asbolus appears to be the nucleus of an inactive comet .
